Page 9: Introduction
• The 020C is a precision instrument. Please handle it with care. • If the 020C will be installed at heights over six feet, be familiar with tower safety and follow safe tower-climbing procedures. • Danger — Use extreme care when working near overhead electrical wires. - Page 10 020C Wind Direction Sensor Use the following procedure to get started. Open Short Cut. Click New Program. Select Datalogger Model and Scan Interval (default of 5 seconds is OK for most applications). Click Next.
- Page 11 020C Wind Direction Sensor Under the Available Sensors and Devices list, select the Sensors | Meteorological | Wind Speed & Direction folder. Select 020C Wind Direction Sensor and click to move the selection to the selected device window. When the sensor points south with the hub and column notches aligned, no installation-offset correction is required.

Page 12: Overview
The built-in electronics provide a voltage source for the potentiometer and amplifies the output signal for transmission over long cable lengths. The 020C includes an internal heater, which provides positive clean aspiration through the bearings, thereby greatly increasing bearing life. It also includes electrical field surge protection that reduces problems associated with static fields, near-miss lightning hits, and poor grounding systems. -

Page 14: Datalogger Programming
(p. B-1) 7.2.1.1 Output Voltage The default output voltage range is 0 to 5 Vdc, which most Campbell Scientific dataloggers can measure. For the CR300 datalogger to measure the 020C, move the jumper block under the outer cover of the main body of the probe. -
Page 15: Siting
020C Wind Direction Sensor Siting Locate wind sensors away from obstructions such as trees and buildings. A general rule is that a horizontal distance of at least ten times the height of the obstruction should be between the wind set and the obstruction. If mounting the sensor on the roof of a building is necessary, the height of the sensor above the roof should be at least 1.5 times the height of the building. -

Page 17: Sensor Check-Out
Tighten the U-bolt if using the CM220 (FIGURE 7-1) or set screws if using the Nu-Rail® fitting (FIGURE 7-2). Attach the sensor cable to the six-pin male connector on the 020C (FIGURE 7-1). Route the sensor cable along the underside of the crossarm to the tripod or tower, and to the instrument enclosure. -
